E30 Zone

So I’m fancying an m54 swap in my E30.

It currently has a m52 in. I was wondering if the swap is much more involved than this would be.

Ideally I would like to use my current drive train.

If you already have an M52 in it already, it should be a reasonably easy swap. I think the main difference with the M54 is the drive by wire throttle, you'll need Fwb accelerator pedal and the associated wiring.
